docs(038): final validation PASS — implementation complete

All 56 tasks (T001-T056) complete: 94 backend + 20 agent tests green,
belief audit 0 errors, 0 orphans, all 7 openapi paths implemented,
24/24 prototype states, INV_1/INV_7 verified. Ready for qa-tester.

+## Final Verification Evidence (Phase 9 gates)
+
+| Gate | Evidence |
+|------|----------|
+| Backend tests | 94 passed (scenario unit + property + belief + API) |
+| Agent tests | 20 passed (tool filter + scenario allowlist) |
+| Ruff (backend + agent) | clean |
+| Belief runtime audit | 0 errors (4 C5 + 9 C4 contracts instrumented) |
+| Belief protocol audit | @RATIONALE/@REJECTED on all C4/C5 (incl. data-model.md) |
+| Semantic rebuild | 8094 contracts, 3804 edges, 0 parse warnings |
+| Orphan audit (scenario scope) | 0 orphans, 0 unresolved relations |
+| OpenAPI drift | all 7 operationIds implemented in `scenario.py` |
+| Prototype | 24/24 state classes covered (18 sections + grouped) |
+| Determinism | repeated + shuffled compile byte-identical |
+| INV_1 | all regions balanced across scenario package |
+| INV_7 | module <400 LOC; validator decomposed (C901 36→5) |
+
+## Blocking Findings
+
+✅ None. All 56 tasks (T001–T056) complete.
+
+## Gate Decision
+
+**Verdict**: ✅ PASS — feature 038 implementation complete; ready for qa-tester orthogonal verification and push.
